pageNotFound

1.5. Under the hood

When TYPO3 detects that a page does not exist, it executes special functions that determine how this situation should be handled. The most common situation is to fetch a dynamic page. Since the error page can be in another domain, TYPO3 puts a proper <base> tag into the page ensuring that the page will display images and links properly.

One problem that arises from fetching error page is logging. If you use Webalizer, you can tell it to ignore this page in reports. However if your log analysis software does not allow excluding certain page you want want to exclude this page using conditional logging as described on the Apache web site (http://httpd.apache.org/docs/2.0/logs.html#conditional)
